Bats don't live in 'houses' like this. They are not birds."Bat houses" almost invariably become wasp nests because bats simply won't live for any extended time in a box with only one exit, nor, particularly warm/safe for hibernation in winter.

The reason they live where they do is because other things CAN'T get them there.They're not going to put themselves to sleep for months in a box that pretty much says "food in here" to a predator.
